Bug description: gmp_init() results 0 on given base and number starting with
0x or 0b
Description:
------------
When calling gmp_init() with a *string* starting with 0x or 0b and a given
base, 0 is returned (except if the base is 16).
Tested with PHP 5.2.3, PHP 5.3 and PHP 5.3-200911141130.
Reproduce code:
---------------
for($base=2;$base<=36;$base++) {
echo '<br>'.$base.': ';
for($i=1;$i<$base;$i++) {
$c=($i<=9?$i:chr($i-10+ord('a')));
$s='0'.$c.$c;
echo gmp_strval(gmp_init($s,$base),$base) . ' ';
}
}
Expected result:
----------------
